Tov all whom it may concern: I

Be it known that I, STEFANUS NIELSEN a sub ect of the King of Norway, and resident of the borough of Brooklyn, city of NeW' York, in thecounty of Kings and State of New York, have invented-certain new and useful Improvements in Type-VVriting Machines, of which the following is a specification.

My invention relates more particularly to the ribbon mechanism of that class of typewriting machines employing a ribbon vibrator or carrier, by which term is meant any device for moving the ribbon to cover and uncover theprinting point.

One object of my invention is to provide a construction wherein a ribbon having a plurality of fields of different characteristics may, at printing operation, be moved to cover the printing point with any desired. field of the ribbon.

Another object is to provide means to dispense at will with the crosswise feed of the ribbon in that class of machines employing a ribbon vibrator and wherein theribbon has both a crosswise and a lengthwise feed.

A further object is to provide means to enable a ribbon of more than one color to be employed in the last named class of machines.

Another object is to dispense at will such machines with the vibratory movement of the ribbon.

and particularly pointed out in the appended claims.

In the accompanying drawings, Figure l is a vertical front to rear sectional view,

'taken about centrally, of one form of typewriting machine embodying my invention. Fig. 2 is a fragmentary front elevation show ing the upper portion of the machine. Fig. 3 is a rear view taken on a plane represented by the line as in Fig. 1, various parts being omitted. 'Fig. 4 is a fragmentary top plan Figs. 5, 6 and 7 are enlarged top planviews similar to Fig. 4 but showingvariou's parts in different positions from those in which they appear in said Fig.4. Fig. 8 is a top lan (I construction of one o the My invention is shown as embodied in a- Monarch typewriting machine but it may be adapted to other forms of writing machines.

Inthe drawings, 1 is the base of the machine supporting corner posts 2, which sus: taina top plate 3. Key levers 4 are fulcruined on a fulcrum plate 5 and each key lever is provided with a restoring spring 6. Pivoted at 7 to each key lever is a sub-lever 8, the lower portion whereof c'o-acts with a fixed abutment 9 and the upper portion whereof is connected by a link 10 with a type bar 11 which is one of a segmentally arranged series. Each type bar 11 is seated in a radial slot 12 formed in a segmental type bar support 13, the heels ofthe type bars being perforated to receive a segmental pivot wire 14 which is contained in a groove cut in the top face of the segmental sup ort 13. Instead of this mode of pivoting t e type bars on a fulcrum wire said bars may be provided with separate hangers and pivots.

.The type bars are normally supported at their outer ends by a segmental typerest 15 and said bars are adapted to cooperate with a platen 16 mounted in a carriage 17 ,saidjcari which are fixedly secured to the top plate 3.

The carriagel? is provided with a feed rack 22 which normally meshes with a pinion 23, the latter being operatively connected with an escapement wheel 24. Adapted to cooperate with the escapement wheel are feed dogs 25 mounted on a pivoted dog rocker 26 which has a horizontal arm 27 connected by a rod or link 28 with the rearwardly extending arm 29 of a universal bar frame 30 pivoted in the base of the machine at 3.1. The frame 30 carries a universal bar 32 which extends from side to side of the machine beneath the spacing levers (not shown). and the series of key levers 4, and is adapted to be actuated by said levers when the'latter aredepressed, ashappens during each printing or spacing operation. The carriage 1,7 is

connected by a strap 33 with a spring drum I .tuated the escapement mechanism just described is caused to be operated in a known manner and thereby to permit of letter space Y 55 elements hereinafter called'a cam member; movements of the carriage.

spools are connected with similar gear trains .ing pinions 43 on the driving shaft 44.

I wind the ribbonthereon.

Ribbon spools S35 arranged above the top 1 plate 3 at cachside of the machine and forwardly of the platen, receive a ribbon 36, which, as herein shown, is divided longitudi nally into fields a and b of different characteristics, that is to say, the field a may be of one color such as black, and the field I) of another and dille rent color such as red, or the lield (I may be copying ribbon and the field I) record ribbon, etc. The ribbon 36 may be fed longitudinally from either spool to the other by any suitable means. The drawings illustrate a ribbon feed mechanism which is similar to that employed in the Monarch typewriting machine and which. is explained in ll. S. patent to Jacob Felbel & arl (labrielson No. 703,339, dated June 24, 1902. Each ribbon spool 35 is carried by and turns with an u 'irighl shaft 37 which rotates in a fixed bearing and has secured at its lower end a small beveled gear 39. The gear 39 meshes with a beveled pinion 40 secured to the forward end of a horizontal shaft 41, which shaft carries at its rear end a beveled pinion 42 which is adapted to mesh with a beveled driving pinion 43 mounted on a driving or power shaft 44. Rotary move ment is transmitted tothe shaft44 by beveled pinions 45 and 46, the pinion 45 being operatively connected with the driving shaft and the pinion 46 with the spring drum 34. p It will be understood that both ribbon which are adapted to be actuated from driv- As explained 'in the above cited patent the driving or power shaft 44 is capable of longitudinal movement, and it is further to be understood that the longitudinal position of said shaft determines which driving pinion 43 will bein mesh with its cooperating pinion 42 and which ribbon spool will be turned to Midway between the ribbon spools the ribbon 36 is threaded through a ribbon vibrator or carrier 47"which is guided and supported in the upright arms 48 of a supporting )racket 49, the latter being secured to the top plate by screws 50. The lower portion of the'vibrator 47 is slotted and provided with a crosswise pin 51 which engages with the slotted forward end of an operating lever 52 pivoted at 53 in a lug 54.depending from the under side of the top plate. The rear arm of the o crating lever 52 is formed with an elongate( slot 55 having at its forward end a downwardly extending portion 55. Engaging with this slot 55 is a pin or stud 56 carried by and secured in the top of a link 57, the. lower end of said link being pivoted at 58 to the rear arm. 29 of the universal bar frame. The, link is provided near its 11 )per end with a forwardly and downwardly iient arm 59. The link 57 is adapted to be swung about its pivot 58 in order to cause the stud 56 to move longitudinally of the slot 55 so as to engage the operating lever 52 at varying distances from the pivot or fulcrum 54 and thereby to vary the throw of the ribbon carrier orvibrator' 47. This swinging or vibratory movement of the link 57 is caused by an eccentric controller or member 60 which is slidably mounted upon the driving shaft 44 and which is adapted to cooperate with the strap formed by the link 57 and its bent arm 59. The eccentric controller 60 comprises a comparatively narrow eccentric working face 61, a tapered or cam portion 62 and a sleeve portion 63, the latter being formed with a circumferential groove or depression 64. A screw 65 passes into the sleeve portion 63 of the member 60, and enters an elongated slot or groove 66 in the driving or power shaft 44. The eccentric member 60 is thereby slidably connected with the power shaft 44 and is caused to rotate with said shaft but may be moved longitudinally of the shaft without affecting the latter. The shaft 44 may also be moved longitidinally without affecting the member 66'. The longitudinal movement of the eccentric member 60 is controlled by a switching member or slide 67 which comprises, first, a vertically. disposed arm 68 terminating at the top in a perforated collar portion 69 and at the lower end in a fork 70 which partially surrounds the depression 64 and the member 60; and second,'-a horizontally disposed arm 71 extending rearwardly from the vertical arm 68. As seen in Figs. 3 to 7 inclusive, the arm 71 comprises a rearwardly extending portion 72, a portion 73 at right angles thereto and parallel with the driving shaft 44, an obliquely disposed and forwardly extending portion 7 4, a short portion' 75 parallel with'the portion 73, another and shorter obliquely disposed and forwardly extending portion 76, and, finally, another short portion 77 parallel with the portions 7 3 and 75. The ull and )ush rod 78 has its inner end fixedl y secure in the collar portion 69 of the switching member or slide 67 and bears in the flange of the top plate 3, passing through the latter and terminating exteriorly of the inachine in a finger button 79. The rod 7 R is formed with notches or depressions 80, 81, 82 and 83 with which a locking spring 84 is adapted to engage, said locking spring being secured to the top plate by a screw 85. The

rod 78 also has a bearing inv a lug 86 dependparts positioned as shown in lfligs. 3 and/1,,

the ribbon will be fed progressively crosswise during successive printing operatlons "and some of the type impressions will be made on the field a which may, forexam le, be black in color, other impressions wil be made on the field b which may, for example, be red in color, while yet other impressions will be made partly on one field and partly on the other. By this mode of operation a variegated or party-colored effect may beobtained which may be desired in some styles of ornamental typewriting; In most forms of typewriting, however, it is desirable to print in one color at a time. If as suggested the two color ribbon be, as is most usual, a black and red ribbon, and it be desired to print only on the-black field, the pull -rod;78 is drawn outward (or to the left as viewed in Figs. 3 to 7, inclusive) until the locking spring 84, which normally is in engagement with the first notch 80 engages with the second notch 81. As the rod 78 moves to the left it carries with it the switching member 67, and the eccentric member 60 participates in this movement by reason of the connection formed by the engagement of the fork with the depression 64 of said eccentric member. ment of the switching member disengages the eccentric face 61 from its strap and permits the spring 88 to draw the link. 57 backward so that the pin or stud 56 is main-.

tained thereafter at the rear of the slot 55. The parts'will now be -ositioned as indicated depression of a key lever 4 the'ribbon vibrator will be raised to the same height. The mechanism is so'proportioned and adjusted that this movement of the ribbon vibrator causes the black field a to always cover the printing point and the path of the type impressions -will be,in a straight line longitudinal of the ribbon field a.

If it be desired to print upon the red field b of the. ribbon the rod 78 is drawn still further outward-or to the left until the spring 84,. disengaging from the notch or depression 81, engages with the notch 82. Drawn by the rod 78 the switching member is moved still further leftward. It will be noted upon an inspection of Fig. 5 that at the beginning of this new movement the link 57 is at the elbow formed by the junction betweenz'the' portions 73 and 74 of the arm 71 of the switching member 67. As the switching member moves to the leftthe oblique ortion 74, acting on the link 57, cards sald ink forward longitudinally of the'lever 52 and against the pull of the s'pringfSS. and forces the link upon theshortportion 75aga1ns't The leftward move- 'therewit field b to the printing point and the path of the type im ressions will be in a straight line longitudinal of said ribbon field I).

, At times it may be desired to maintain the vibrator quiescent in normal position so that a stencil may be work'w-ithout the, lnterposition of the ribbon between the type and platen at each printing operation. To accomplish this result the pull r0d78 is pulled out still further to the left until the locking spring 84 engages with the last notch 83 in said rod. The switching member 67 is drawn with the rod 78 still ther outward or to the left and the oblique portion 76 of the arm 71 acting u on the link 57 cams said link still further forward longitudinally of the lever 52 and forces the link upon th'e'portion 77 of said arm 71, against which portion the link is maintained by the pull of the spring 88. The parts will now be positioned as indicated in Fig; 7 wherein it will be noted that the stud 56 has been moved forward still further in the slotv 55 of the operating link 52 so that said stud will now. beabove the downwardly extending portion 55 0f the said slot. At each depression of a key lever 4 the link 57 is drawn downwardly, carrying with it the stud 56, the latter moving downward in the forwardly extending portion 55 of the slot 55. The parts are so 'roporprepared for mimeograph tioned that the stud 56 reaches the imlt of ing spring to successively reengage with the notches 82, 81 and 80, the reverse of the operations hereinbefore detailed will take place and at .each-key'depression the ribbon vlbrator will be moved so as to bring either the red. field, the black field or progressively the whole width of the ribbon to the printing point according as either the notch'82, the notch 81 or notch 80 be in engagement with the locking'spring 84. The tapered face 62 enables the eccentric member to readily find its stra and effect a certain connection tion of printing rear edges of the In Fig. 8 I have illustrated a modification of the means (the arm 71.) employed for positioning the link 57 longitudinally of the ,operating lever 52. Referring to said figure it will be noted that the arm 71 is re laced on the inner end of the slide rod 78 by a cam member 89, said cam member being provided with an open-ended slot comprising a cam'ming portion 90, a dwell portion 9]., a second camming portion 92, a dwell 93, a camming portion 94 and a dwell 95. The slot is so proportioned that the front and link 57 will contact slightly with the front and rear Walls of the slot so that the said link is positively positioned fore and aft of the machine by the camming member 89. The cam 90 guides the link into the slot and the cams and dwells 91, 92, 93, 94k and 95 correspond respectively to the parts 73, 74, 75, 76 and 77 in the first described form. This modi. fied construction enables the draw spring 88 to be dispensed with.

Various changes in the construction and arrangements of the parts may be efiected and parts of the invention may be used without other parts, all without departing from the spirit of my invention.
